Promise Round Diamond Engagement Ring

Please contact us directly should you require a ring in a size that is not shown on the website.

A harmonious composition of light and form, the Promise Engagement Ring contrasts the exceptional brilliance of a 1.92 carat certified round brilliant-cut diamond with the refined geometry of tapered baguette-cut side stones. Set in luminous white gold, the side stones are perfectly positioned to create clean, architectural lines that guide the eye—and the light—toward the center stone, intensifying its radiance.

With a total carat weight of 2.49, this setting is the embodiment of classic elegance, crafted for those who value sophistication with enduring significance.

Every diamond in our engagement collection is hand-selected by a member of the Fuster family, ensuring exceptional quality, provenance, and emotional integrity.

Each Fuster creation is unique. As a result, size, carat weight and stone qualities can vary slightly from one to another. For detailed information, please contact us or book an in-store appointment.
